processing does not perform necessary authorization checks for an authenticated user, resulting in escalation of 
privileges. On successful exploitation the attacker could critically impact both integrity and availability of the 
application.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
